nsfilecoordinator

When a new file is created inside the package, either programmatically using NSFileManager with proper NSFileCoordination methods or via Finder i only got -presentedSubitemDidChangeAtURL: event, but not seeming so obvious in this case -presentedSubitemDidAppearAtURL: . Is this an expected behavior or i am doing something wrong? The comments on
